Just to conclude, I managed to get one end of the fuse soldered to the white wire, and it tested for continuity to that point. Trying to crimp or solder onto the end of the super fine coper wire proved impossible. It's kept breakign and got to a point where there was no accessible wire left. So basically I didn't fix the blender, but I should have, and I learned a lot on this process. I should have extracted the motor from the housing, then access would have been much easier, and i may have succeeded. I forgot the plate holding the spindle in place was reverse thread, so I thought I couldn't remove it. Discovered this too late.
Anyway guys, thanks a bunch
On to the next repair
